Hi again; I found a statement saying
-make a post volume
-scroll down to screen space reflections
-change quality from 50 to 100
-and now the magic…type in “r.ssr.quality 4” into the console command and then it works!
The thing is…if you go from 50 to 100 in the post…nothing happens when you dont tell the renderer that it is allowed to render them at max settings, which is quality level 4.
So you need to do both and it works
